Homosexual behavior is defined as genital contact or genital manipulation between same-sex individuals. In nonhuman primates, it may regulate social relationships by serving as a means of reconciliation, tension alleviation, or alliance formation. Grappling is a rare and complex behavior, which most frequently occurs between same-sex individuals of the genus Ateles and can include mutual manipulation of the genitalia. Here we report three cases of penile–anal intromission during grappling… 

Anecdotic observations of homosexual behaviour among male capuchin monkeys (Sapajus sp.)

Four events of male-male mounts were observed, involving six individuals — two juveniles and four adults, which do not seem related to hierarchical or age group factors, but could be related to getting access to the experimental apparatus.

Sociosexual behaviour in wild chimpanzees occurs in variable contexts and is frequent between same-sex partners

Although sociosexual behaviour may be less frequent in chimpanzees than in bonobos, and bonobos remain distinct in their genito-genital rubbing, the findings suggest that soci homosexual behaviour is a regular part of chimpanzee behaviour.

Predation Attacks on Wild Spider Monkeys (Ateles geoffroyi)

Observations show that predation occurs in the study area and therefore behavioral strategies are likely to be in place to reduce predation risk, and are further evidence that terrestrial predators are a threat for both young and full-grown spider monkeys.

The De-Scent of Sexuality: Should We Smell a Rat?

Although some ideas in the proposed connection between the transient receptor potential cation channel 2 gene (TRPC2) and same-sex sexual behavior in primates are supported, greater caution is advocated when interpreting available data on SSSB.

The De-Scent of Sexuality: Did Loss of a Pheromone Signaling Protein Permit the Evolution of Same-Sex Sexual Behavior in Primates?

It is indicated that loss of TRPC2 function in developing mice leads to the loss or attenuation of sexually dimorphisms in the adult brain, which may help to understand the biological underpinnings of SSSB.

Using multiplex networks to capture the multidimensional nature of social structure

This work uses a multiplex representation of interactions among the members of a group of wild Geoffroy’s spider monkeys, to study their social structure and concludes that the multiplex approach improves on previous methods by retaining valuable information from each interaction type and how it is patterned among individuals.

Variation in communicative complexity in relation to social structure and organization in non-human primates

Communicative complexity relates to social complexity, as individuals in more complex social systems either use more signals or more complex signals than individuals living in less complex ones.



Age related variation in male–male relationships in wild spider monkeys (Ateles geoffroyi yucatanensis)

Evidence is found that younger males are attracted to older males, probably because they value relationships with older males more than the reverse, but they are also at risk, suggesting relationships between younger and older males are more risky.

Use and function of genital contacts among female bonobos

It is suggested that genital contacts can be used to investigate both quality and dynamics of dyadic social relationships among female bonobos, and shown rank-related asymmetries in initiation and performance of genital contacts supporting the social status hypothesis.

Male mating tactics in spider monkeys: sneaking to compete

Investigation of the mating system and male mating tactics for a population of wild spider monkeys shows that clandestine copulations are one behavioral solution to the complex problem of gaining mating exclusivity and, probably, exercising mate choice.

Male philopatry in spider monkeys revisited.

It is suggested that in spider monkeys male immigration may occur under certain demographic circumstances, contributing to a view of greater flexibility in their social system than previously appreciated.

Homosexual behaviour in wild white-handed gibbons (Hylobates lar)

Homosexual mounting in apes and prosimians is rare. Male-male mounting was observed between an adult male white-handed gibbon and an adolescent male in the same group. The behaviour is discussed in

Intragroup lethal aggression in wild spider monkeys

We report the first evidence of intragroup coalitionary aggression leading to the death of a wild young adult male spider monkey. During a long‐term study of a well‐habituated community at the Otoch

Male Homosexual Behavior in a Free-Ranging All-Male Group of Japanese Macaques at Minoo, Japan

This first report of male homosexual interactions in an all-male group of Japanese macaques contributes to the growing database used to provide insights into the developmental processes, causal mechanisms, adaptive significance, and phylogenetic pathways of same-sex sexual behavior.

Male-directed infanticide in spider monkeys (Ateles spp.)

Given the potentially close genetic relationships among adult males within spider monkey groups, and the need for males to cooperate with one another in territorial interactions with other groups of related males, infanticide may be expected to occur primarily where the level of intragroup competition among males outweighs that of competition between social groups.

Social relations and behaviours of adolescent female pygmy chimpanzees (Pan paniscus) that migrated between unit groups were studied at Wamba, Zaïre. Each immigrant female selected one particular

Raiding parties of male spider monkeys: insights into human warfare?

The first cases ever witnessed of raiding parties of male spider monkeys, a species expected to show such a behavioral tendency, are reported, to support the notion that lethal raiding is a convergent response to similar socio-ecological conditions.
